live there, right? so there's no search engine optimization. there's nothing you can find on google in terms of what people say in your neighborhood. you have to prove that you live within those boundaries and then you get access. >> but still, you're not completely safe. your address is out there. some of the people that are lingering and looming on some of these trails probably live in that neighborhood and do have access to nextdoor. they may have criminal records. they may be a sex offender. is it possible for you to make sure that those people do not, you know, get into this community? because they can easily stock people. >> there are two things. first of all, the only thing you're required to reveal about yourself is your name and your street name. you don't have to reveal your exact street address. the sex thing is, when it comes to addresses of sex offenders, we've integrated 350 state databases of those address and if you try to join from one of those addresses, we don't allow you to do that. so we've done a lot of work to make this as safe and intimate a place as we can.
